[1] On 29 January 2010, Block J of 45 Ma Tau Wai Road, a rundown five-storey residential building in Hok Yuen, collapsed with little warning, resulting in the deaths of four people.
Renovation work was being carried out on the commercial unit located on the ground floor of the building, when construction workers noticed signs of an imminent collapse and rushed out to raise the alarm.
Several hundred emergency workers were deployed in the ensuing rescue operation, which had to take place under adjacent buildings that were themselves subject to collapse at any moment.
Temporary reinforcements were erected to support and stabilise the remaining structures to give added protection to the rescue teams.
Residents in the adjoining blocks were subsequently relocated to temporary shelters in the immediate aftermath and then on to interim housing at public estates.
